About Flexion

At Flexion, we're building the intelligence layer that powers the next generation of humanoid robots. Our mission is to accelerate the transition from fragile prototypes to real-world humanoid deployment. We are founded by leading scientists in robot reinforcement learning (ex-Nvidia, ex-ETH Zürich), and backed by leading international VC firms. In just over one year, we’ve gone from our first line of code to deploying real humanoid capabilities.

The Role

We’re looking for a IT and Security Engineer to take end-to-end ownership of our internal IT and security infrastructure. You’ll be our first dedicated hire in this space and help us take our IT systems to the next level. You'll also manage our IT contractors as needed so that you have the operational support you need.

This is a unique opportunity to understand and advance the IT infrastructure powering the development of state-of-the-art humanoid robots and AI. You’ll work with Flexion’s robots, GPU workstations, servers, cloud infrastructure, modern networking equipment and robot testing areas. You’ll define policies and processes, implement the controls that matter most, and partner with our engineers and contractors to ensure our internal and cloud environments stay secure without slowing the company down.

You’ll work as part of our experienced infrastructure team consisting of senior software engineers (ex Google, Meta, Amazon).

Key Responsibilities

• Own IT end-to-end: Build and manage reliable IT systems for a growing team (≈50), with clear processes for onboarding/offboarding, access, and support. You’ll collaborate with our software engineers and contractors on the implementation and operations when needed.
• Lead security improvements: Build the systems that manage Linux laptops, workstations and servers (provisioning, patching, hardening, posture, inventory). Define practical security policies and roll out high-impact controls to protect company IP.
• Manage the office network: maintain and improve our UniFi-based network (Wi-Fi, segmentation, firewalling, guest access) for high uptime, strong security and robust connections to our robots.
• Baseline AWS security: manage foundational AWS security (org/IAM hygiene, VPC/security groups, EC2 lifecycle guardrails) in partnership with engineering.

Requirements

• 3+ years experience in an IT or security role (engineering or system administration), with meaningful ownership of IT environments.

• Strong Linux administration skills: Configuration and automation (e.g. Ansible), system hardening, updates, and troubleshooting.
• Solid fundamentals in networking (DNS, DHCP, VLANs, Wi-Fi, firewall concepts).
• Practical security mindset: ability to define policies, prioritize controls, and implement security improvements that scale with a growing team.
• Comfortable working in a high-ownership role: you can set direction, deliver, document, and iterate.

Additionally, the following skills are a plus

• Familiarity with common security tooling: EDR, vulnerability scanning, centralized logging, secrets management, and password managers.
• Experience running identity and access management in a company setting (Google Workspace preferred), including joiner/mover/leaver workflows and permission design.
• AWS security fundamentals: IAM best practices, VPC/security groups, baseline monitoring/alerting, and secure EC2 lifecycle practices.
• Scripting/automation ability (e.g., Bash/Python) to reduce repetitive operational work.

Benefits

• Competitive compensation
• Enhanced pension plan
• Enhanced holiday & paid leave perks
• Relocation & permit sponsorship
• Central Zürich office with top-tier robotics testing facilities and infrastructure
• Joining Europe's leading robotics team & exposure to never-done-before research
• Energetic, collaborative culture with a bias for action and regular community events
